摘要
日光温室太阳能地温加热技术是应用太阳能聚光装置加热介质水,通过介质水的循环加热土壤温度,从而为日光温室作物生长提供适宜的地温。设计研究加装储能罐的日光温室太阳能地温加热系统,并在天津市静海县进行试验应用。效果显示该系统可以有效提高日光温室的地温,冬季地温可以保持在15℃以上,满足果菜生产的地温需求。
Solar geothermal heating technology used in sunlight greenhouse is the application of solar concentrator heating medium water,soil temperature is heated by circulating medium water,so as to provide the appropriate soil temperature for sunlight greenhouse crop growth. Solar geothermal heating system used in sunlight greenhouse with energy storage tank was designed and researched,and its effects were tested in Jinghai county of Tianjin city. Results showed that the system could effectively improve the soil temperature of sunlight greenhouse,the soil temperature could be maintained at 15 ℃ in winter,it was to meet the demand of fruit vegetables production.
